IMPROVEMENT IN SEAL-FASTENINGS.

Specification forming part of Letters Patent No. 202,267, dated April 9,1878; application filed January 26, 1878.

To all whom it may concern:

Be it known that I, SANFORD KEELER, of East Saginaw, Saginaw county,Michigan, have invented a new and useful Improvement in Seal-Fasteningsfor Doors, of which the following is a specification:

The object of my invention is to provide a simple, cheap, and effectiveseal for application to the fastenings of the doors of cars or otherstructuresan object which I attain in the following manner, referencebeing had to the accompanying drawing, in which Figures 1, 2, and 3 areperspective views of my improved seal applied to different forms ofcar-door fastenings; and Fig. 4, a View illustrating the method ofcompleting the seal.

A represents part of the door of a car or other structure, and B part ofthe frame of the door, the latter having a staple, to which is adapted ahasp on the door in the usual manner. To the hasp and staple is adapted,as shown in Figs. 1, 2, and 3, a strip, D, of strong sheet metal, thisstrip having an opening near each end, so that when the ends of thestrip are brought together the stem of a rivet, b, may be passed throughthe openings. This strip of sheet metal is intertwined with both haspand staple, as shown in the drawing, in order that the fastening may bemore secure than ordinary seal-locks of this class. The rivet b is madeof lead or other soft metal or alloy, so that it may be readily rivetedupon the strip, and thereby secure the ends of the same firmly together.

In order to effect the riveting operation I employ a pair of pinchers,as shown in Fig. 3, one of the j aws, d, of this pair of piuchers havinga recess adapted to the head of the rivet, while the other jaw, c, hasformed in it adie composed of any letters, numbers, or marks which itmay be desired to impress upon the rivet in order to form a seal, theoperations of riveting and sealing being thus performed simultaneously.

When the above-described sealing device is used on a car, access to theinterior of the car cannot be gained without either removing the rivet bor severing the strip D, thus in either case indicating to the authoritywhose duty it is to examine the seals when and between what stations thecar-door has been opened.

I do not desire to claim, broadly, the combination of the sheet-metalstrip and soft-metal seal; but

I claim as my invention- The combination of the hasp and staple, thesheet-metal strip D, arranged to embrace both hasp and staple, andhaving openings near its opposite ends, and the soft-metal rivet I),having a shank adapted to the openings in the strip, all substantiallyas set forth.

In testimony-whereof I have signed myname to this specification in thepresence of two subsoribin g witnesses.

SANFORD KEELER.
